Martinez's friend told police that they were walking in the 8600 block of Beechnut when two men approached, pulled knives and demanded their wallets, according to a criminal complaint filed after the incident.

The friend told investigators that he began to run and looked back to see Martinez fighting the two men. The friend returned a short time later and found Martinez lying in the street bleeding, the complaint stated.

Martinez, stabbed in the back, chest, neck and abdomen, later died at Memorial Hermann Southwest Hospital.
